Poulan Pro PR5020 Bar and Chain Tips (5 Expert Hacks)

Understanding Your Poulan Pro PR5020

Before diving into the hacks, let’s quickly review the basics of your chainsaw. The Poulan Pro PR5020 typically features a 20-inch bar and is powered by a 50cc engine. It’s designed for felling small trees, limbing, and cutting firewood. Understanding its limitations is crucial for preventing unnecessary wear and tear. For instance, attempting to fell trees larger than the bar length can lead to bar pinching and chain damage.

Hack 1: Master the Art of Chain Sharpening

A dull chain is the enemy of efficient cutting and a major cause of bar wear. I can’t stress this enough: a sharp chain is a safe chain! A dull chain requires more force, increasing the risk of kickback.

Why Sharpening Matters

Sharpening restores the cutting edge of the chain’s teeth, allowing them to slice through wood fibers instead of tearing them. A sharp chain produces larger, more consistent wood chips. If you’re seeing sawdust instead of chips, it’s a clear sign your chain needs sharpening.

Tools You’ll Need

Chainsaw file (size specific to your chain): Typically, a 5/32″ or 3/16″ file is used for the PR5020. Consult your owner’s manual for the exact size.
File guide: This helps maintain the correct angle and depth while filing.
Depth gauge tool: Used to check and adjust the depth of the rakers (also known as depth gauges or gullets).
Vise (optional but recommended): Secures the bar for easier sharpening.

Step-by-Step Sharpening Guide

Secure the bar: If using a vise, clamp the bar securely. Otherwise, engage the chain brake and rest the saw on a stable surface.
Identify the cutters: Each cutter has a top plate and a side plate. You’ll be sharpening both.
Position the file: Place the file guide on the cutter, aligning the file with the guide’s markings. The file should be angled slightly upwards (typically around 30 degrees) and inwards.
File the cutter: Using smooth, consistent strokes, file the top plate of the cutter. Apply gentle pressure on the forward stroke and release on the return stroke. Count the number of strokes for each cutter to ensure consistency. I usually aim for 3-5 strokes per cutter.
Repeat for all cutters: Sharpen each cutter on one side of the chain, then flip the saw (or reposition the vise) and sharpen the cutters on the other side.
Check the depth gauges: After sharpening, use the depth gauge tool to check the height of the rakers. If they’re too high (protruding above the tool), file them down until they’re flush with the tool. This is crucial for preventing kickback.
Test the chain: After sharpening, test the chain on a piece of softwood. A sharp chain should pull itself into the wood with minimal pressure.

Pro Tips for Sharpening

Consistency is key: Maintain a consistent angle and number of strokes for each cutter.
Don’t overheat the chain: Avoid excessive filing, which can damage the temper of the steel.
Clean the chain: Before sharpening, clean the chain with a wire brush to remove dirt and debris.
Consider a chainsaw sharpener: For frequent sharpening, a powered chainsaw sharpener can save time and ensure consistent results.

Common Mistakes to Avoid

Using the wrong file size: This can damage the cutters and affect the chain’s performance.
Filing at the wrong angle: This can create a dull or aggressive cutting edge.
Ignoring the depth gauges: This can increase the risk of kickback.
Sharpening a damaged chain: If the chain is severely damaged (e.g., broken teeth, bent links), it’s best to replace it.

Takeaway: Regular chain sharpening is essential for efficient cutting, safety, and extending the life of your Poulan Pro PR5020. Aim to sharpen your chain every few tanks of gas, or more frequently if you’re cutting dirty or abrasive wood.

Hack 2: Bar Maintenance: Flipping, Cleaning, and Lubricating

The chainsaw bar is a critical component that supports and guides the chain. Proper bar maintenance is essential for preventing premature wear and ensuring smooth cutting.

Why Bar Maintenance Matters

The bar groove, which guides the chain, can accumulate dirt, debris, and pitch, leading to increased friction and wear. The bar rails, which support the chain’s cutters, can also wear down over time, affecting the chain’s ability to cut straight.

Flipping the Bar

Flipping the bar regularly ensures even wear on both sides. I recommend flipping the bar every time you sharpen the chain.

Takeaway: Regular bar maintenance is crucial for extending the life of your chainsaw bar and ensuring smooth, efficient cutting. Flipping, cleaning, and lubricating the bar should be part of your routine maintenance schedule.

Hack 3: Chain Tension: Finding the Sweet Spot

Proper chain tension is vital for safe and efficient chainsaw operation. Too loose, and the chain can derail; too tight, and it can overheat and break.

Why Chain Tension Matters

Correct chain tension ensures the chain engages properly with the bar and sprocket, allowing for smooth cutting and preventing premature wear.

Checking Chain Tension

The ideal chain tension is when the chain is snug against the bar but can still be pulled around by hand.

Step-by-Step Chain Tension Adjustment

Loosen the bar nuts: Loosen the bar nuts slightly, but don’t remove them completely.
Adjust the tensioning screw: Locate the chain tensioning screw, usually located on the side of the chainsaw near the bar. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.
Check the tension: Pull the chain away from the bar at the midpoint. You should be able to pull the chain out about 1/8 inch (3mm).
Tighten the bar nuts: Once the chain tension is correct, tighten the bar nuts to the proper torque (refer to your owner’s manual).
Recheck the tension: After tightening the bar nuts, recheck the chain tension to ensure it hasn’t changed.

Pro Tips for Chain Tension

Check tension frequently: Check the chain tension every time you refuel the chainsaw.
Adjust tension when the chain is cold: The chain expands as it heats up, so adjust the tension when the chain is cold.
New chains stretch: New chains will stretch more than older chains, so you may need to adjust the tension more frequently during the first few hours of use.

Common Mistakes to Avoid

Over-tightening the chain: This can cause the chain to overheat and break.
Under-tightening the chain: This can cause the chain to derail.
Adjusting the tension with a hot chain: This can lead to inaccurate tension adjustments.
